GeForce 930M vs GeForce 9500 GT 1GB GDDR3

Intro

The GeForce 930M has a core clock frequency of 928 MHz and a DDR3 memory speed of 900 MHz. It also makes use of a 64-bit bus, and uses a 28 nm design. It is made up of 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Compare those specs to the GeForce 9500 GT 1GB GDDR3, which has core clock speeds of 550 MHz on the GPU, and 800 MHz on the 1024 MB of GDDR3 memory. It features 32 SPUs as well as 16 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 9500 GT 1GB GDDR3 should perform much faster than the GeForce 930M overall. (explain)

GeForce 9500 GT 1GB GDDR3 25600 MB/sec
GeForce 930M 14400 MB/sec
Difference: 11200 (78%)

Texel Rate

The GeForce 930M is quite a bit (approximately 153%) more effective at texture filtering than the GeForce 9500 GT 1GB GDDR3. (explain)

GeForce 930M 22272 Mtexels/sec
GeForce 9500 GT 1GB GDDR3 8800 Mtexels/sec
Difference: 13472 (153%)

Pixel Rate

The GeForce 930M will be quite a bit (more or less 69%) more effective at full screen anti-aliasing than the GeForce 9500 GT 1GB GDDR3, and also will be able to handle higher resolutions without slowing down too much. (explain)

GeForce 930M 7424 Mpixels/sec
GeForce 9500 GT 1GB GDDR3 4400 Mpixels/sec
Difference: 3024 (69%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
